ROTARY BRUSH.

Specification of Letters Patent.

Patented May 14, 1907.

l'o all whom t Wawy concern:

Be it known that I, EDWARD E. RICE, a citizen of the United. States, residing in New Durham, county of Stratford, and State of New Hampshire, have invented an Improve,- ment in Rotary or Wheel Brushes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel durable and highly eiiicient rotary or wheel brush, of a simple and relatively inexpensive construction, and particularly adapted for polishing or cleaning metal, such as castings, and metal articles of various kinds. As will appear hereinafter,

however, the construction embodied in my present invention can be readily adapted for rotary brushes designed for other uses.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out` in the following claims.

Figure 1 is a side elevation of a rotary brush embodying my invention and particularly adapted for cleaning and polishing metal, a portion of the hub being shown in section, and the brush wires or iilaments, being shown fully for only a portion of the circumference; Fig. 2 is a face view of the hub, showing only the lower ends of a number of the groups of wires and the means for retaining the same in the hub Fig. 3 is an enlarged sectional detail on the line 3 3, Fig. 2, and Fig. 4 is a detail, partly in section, of a modiiication to be described.

, In the present embodiment of my invention I make a cylindrical hub 1, preferably of wood on account of its cheapness and ease of manipulation, and provide it with a central bore 2 to receive the rotatable shaft on which the brush is mounted when in use. The hub is made of suitable width according to the Width of the working face desired, and radial sockets or seats 3 are drilled, in the hub, said socketsbeing preferably arran ed in parallel rows or series transverse to t e face ofthe hub. Herein I havel 'shown four seats or Sockets in each row. A series of transverse slots or saw-cuts 4 is then formed in `the hub, one for each series of sockets, eXtendi from one tothe other side of the hub, sai slots being in radial planes and intersecting all of being substantially equal to the depth of the sockets. In finishing up the hub, I may and preferably do leave an annular iiange 5 at each side thereof, the slots passing throughl the flanges, as shown in Figs. 2 and 3. The 6o are placed in parallelism with the axis of the 7e hub, and when a group of sockets is filled I insert a retainer, shown as a thin, iiat bar 8 of suitable met-al in the slot 4, the bar dividing or passing through each bunch of wires within the bend 7, as will be clear from an inspec- 7 5 tion of Figs. l, 2 and 3. The bar is 'then forced inward until it holds Iirmly seated in the sockets all of the wire bunches ofa transverse group or series.

Locking means to hold the bar in place Se against the action of centrifugal'force must be provided, and this is convenientlyT attained-by Wrapping a wire 9 tightly around the hub* a number of times adjacent each flange 5, and fastening the wires by twisting 85 their ends.

Obviously the cross-sectional shape of the bar-locking member is not necessarily circular, as herein shown, the locking means being applied after all of the bars are positioned, 9o

the retainers being preferably inserted in the slots 4 with a driving nt. The locking means also acts as a binder for the hub, draw.

ing the sides of the slots tightly against the retainers, the elasticity the hub is made permitting such action.

The walls of the sockets 3 tightly embrace the roots of the bunch of wires and afford a secure and rigid lateral support therefor, while outward radial movement of the bunches is loe prevented by the retainers.

So long as the locking members hold the retainers cannot work loose, and the retainers maintain the bunches orgroups of wires securely seated in their sockets. 5 grevent any side slip of the locking means.

have shown the usual form of crimped or waved Wires, this being employed to sethe sockets of a row, the depth of each slot portion of each of the wood of which 9 5 The flanges cure a proper abrading or cleaning surface and also to provide a inutual support lor the Wires ot the various groups, prevel'ltijng separations or -voids in the periphery oi" the brush. l nlalic no clainis to the crimped or waved imitan-e, however, as that is a feature in general use in such brushes.

The brush constructed in accordance with my invci'ltiim is of simple coiistruction and. easily produced, it is highly eilicient, and 'very durable.

Instead of using wire :lilanients l may use horse-hair or other suitable Iilanients. the inode of coi'istruction being equally well ada )ted therefor.

lien the .nature of the filaments is such as to preclude :Folding` in the middle one end of each group can be bent or turned over, as at 10, Fig. 4L, and inserted in the socket, and ,held in place by the retainer 8 as before described.. This inode of fastening and bend- 'ing can be used With advantage when the cost of the lilainents, if long enough tofdouble in the middle, would preclude their use.

Ilaving fully described my invention, what I elaini as new and desire to secure by Letters Patent is 1. In a rotary brush, a cylindrical hub having a peripheral iiange at each side of its face,` radial sockets in the face and trans verse slots in tersectingjr groups el' sockets and lying' in radial planes, buncl'm's oll iilainents bent to enter the sockets, lat retaining' ineinbers inserted in the'slots and passing' through thc bln'iclies of lilainents Within their bends, to retain the bunches seated in the sockets, and means embracing,` the l'acc o` the hub within the ilanges to lock the retainers from displacement by centrifugal action.

2. In a 'rotary cleaning and polishing brush, a cylindrical wooden hub l'iaving,l radial sockets ,in its l'aco arranged in transverse rows, and provided with slots in radial planes intersecting the sockets in each row, a bunch of inet-allie wires bent between its ends and inserted :in each socket, llat retaining n'ienibers inserted in the slots and passing through the bunches of' Wires ,in the sockets within the bends, to maintain said bunches seated in the sockets, and. 'Wire wrapped around the ends of and to leek all of the retainers in the slots.

In testimony whereof, I have signed Iny naine to this specification, in the presence of two subscribing Witnesses.
